Ac blower wheel vibrating on 2002 gmc envoy slt!

How hard is it to get the blower wheel out of the housing?it vibrates more as you turn up the speed. maybe the wheel is fine and just out of balance.do i need to adress this asap or can i run the fan on low? i dont have a problem taking it to gm dealer but if i can do it in a timely manner i will do it in my garage. im a service tech for industrial heating an airconditioning company so i understand mechanics, controls, wiring etc. if you could help that would be great.

If you remove the glove box, you can easily access the blower motor. The blower motor is held in by 3 bolts, 2 of the bolts are easy to get to, the third is a little more difficult. I had this same exact problem with mine and all I had to do was remove a bunch of leaves that got into it somehow, but I had all apart and back together within 2 hours, it may not have even been that long. Hope this helps ya.

I have GMC Envoy 2004 model. since few days i have notice that if i drive in a speed more than 100 KMPH, there is a slight vibration. please advise what could be the reason...


possibly a bad u-joint. Sometimes a u joint will feel ok but if it is too tight it can cause a vibration. you will need to remove the shaft to feel if a joint is too tight and binding. Or you have a tire out of balance. Usually a driveline vibration is more of a buzzing high frequency type of vibration the kind that puts your foot to sleep and a tire is more of a wheel speed vibration which is a lower frequency vibration.

Loud noise and vibration coming from behind the glove compartment area


Hmmm, the blower motor is right behind the glovebox. Does the noise and vibration change when you adjust the blower speed?

My fan vibrates on my envoy, it looks like the housing that the serp. belt goes around is loose causing the fan to vibrate, but I can't figure out how to tighten the housing. I tried turning the big...


The tensioner pulley may be faulty. There should be a lot of tension on the pulley to keep the belt tight. If the tensioner can be moved easily, it should be replace.

2006 slt gmc envoy ac problems vent controls anbd


{: ) The popping sound you heard is caused by the sudden movement of an HVAC door, most probably coming from the recirculation door actuator (right dashboard area) or the mode actuator( mid dashboard area). The fan outputs could be normally working, but is being muffled by the incorrect positioning of the HVAC doors, giving an impression that there is fault in the blower controls. In other words, your vehicle is having an air distribution issue.
If there's no conflict in your climate settings, then the trouble may be in the HVAC doors binding or broken, or the actuators faulty or sticking. In both cases, servicing may involve removal of the dashboard to access these HVAC components.
